How to Use the MC68HC812A4 in Special Expanded
Narrow Mode Using the M68HC12AEVB
By Edgar Saenz
Motorola Microcontroller Division
Austin, Texas
Introduction
The MC68HC812A4 (812A4) is designed primarily as an expanded
mode microcontroller. It can be operated in expanded narrow mode for
8-bit peripheral devices and in expanded wide mode for 16-bit peripheral
devices.
The M68HC12A4EVB (A4EVB) is designed to accommodate expanded
narrow mode of operation, although in the factory it is configured in
expanded wide mode.
The steps to set up the evaluation board are described in this
engineering bulletin. They are designed to help guide users to configure
emulation RAM (random-access memory) in expanded narrow mode
and to utilize a third-party debugger to debug in C language.
